In managing and implementing all resource programs, BLM must consider the Land Health Standards described in Arizona Standards for Rangeland Health and Guidelines for Grazing Administration. The Land Health Standards were developed, pursuant to 43 CFR 4180, through a collaborative process involving BLM’s staff and the Arizona Resource Advisory Council (RAC). The Land Health Standards were approved by the Secretary of the Interior in April 1997. These standards have been developed to determine the characteristics of healthy ecosystems on public lands and management actions to promote them. When approved, the Land Health Standards became BLM Arizona policy, guiding the planning for and management of BLM-administered lands. The Land Health Standards, therefore, have been incorporated into this Approved RMP . Listed below are the standards that describe the desired conditions needed to encourage proper functioning of ecological processes. These standards guide the management actions for all resource programs.
